I was in contact with Cindy via the airbnb app. She scheduled the maid to check me into the room and her brother gave instructions to the taxi driver on how to get to the studio apartment.

I booked the place because it was close to the BTS Udom Suk (E12) station (about 700m according to my iPhone Google Maps app). The taxi ride from the airport cost 320 Baht (250 meter, 50 driver, 20 toll).
On my return to the airport, I used BTS (E12 to N2 for 52 Baht) and then transferred to the airport rail (N2 to BKK airport for 45 Baht). The taxi was definitely faster, but if you aren't in a hurry, and want to view the city, the train ride is doable.

Seeing Bangkok by BTS was good. For 130 Baht, you can get an unlimited use 1-day pass. I went to the Siam shopping mall, the big open market within walking distance of Mo Chit (N8), and rode the river boats near Saphan Taksin (S6). However, if you go out to enjoy night life, the BTS train stops by 24:00.

The place was in a convenient location. The building isn't new, but I felt safe in the area. I think the place was a good value for the money spent. The food stands near the apartment were a good value too.

I guess one concern is that the bed felt a little weak. The frame seemed a bit fragile. Also, I never got any hot or warm water to work in the shower. Other than that, I didn't have any major issues.
